The purpose of this stuty is to evaluate the stage of seminiferous epithelium in adult rat testis.The cellular association was defined by the developmental stage of the spermatids,which themselves were characterized by their staining with the PAS (Periodic Acid Schiff) technique.According to the criterion of Clermont and Russell,the developmental stages can be easily identified by this technique.A cycle of the seminiferous epithelium could be divided into 14 periods,each of these periods was found to have a well defined cell association.By using this technique,researchers can learn the more precise features in rat spermatogenesis.
